The Passport Experience is your personal guide through the wine trails of Maryland. It is a self-guided adventure that gives you the opportunity to experience the rich and unique culture that each region has to offer. Take a weekend (or two) to get away and explore the local attractions, eat at some neighborhood hot-spots, and of course, indulge in great, locally-produced wine.
